DEFINITIONS

TROCHALOPTERON
(Leiothrichidae; Ϯ Scaly Laughingthrush T. subunicolor) Gr. τροχαλος trokhalos  round, bowed; πτερον pteron  wing; "* In a list of specimens now on their way from Mr. Hodgson, I find three species mentioned, by the names leucopophlus (Quære leucolophos), erythropterus, and subunicolor; this last, with setafer and others, constituting Mr. Hodgson's division Trochalopteron, the propriety of adopting which name will depend on whether Mr. Swainson's Crateropus Reinwardii be considered admissable into the group, in which case it must bear the appellation Crateropus.  The specimens adverted to have since arrived, but Tr. leucopophlus (?) and erythropterus are not among them; and of Tr. subunicolor, a nestling specimen only is sent, of a species nearly allied to Tr. erythrocephalus, chrysopterus, and affinis, especially to the latter, but having a shorter and thicker bill than in that bird." (Blyth 1843); "Trochalopteron Blyth, 1843, Journ. Asiat. Soc. Bengal, 12, p. 952, footnote. Type, by subsequent designation (Baker, 1930, Fauna Brit.
